32- and 64-bit JVM Support

The Serena Release Automation server must use the 32-bit JDK for the Windows 2003 64-bit server; the 64-bit JDK can be used for agents. Because Serena Release Automation does not require a multi-gigabyte heap, there is little advantage to using a 64-bit JVM. For 64-bit Windows installations, Serena Release Automation uses a 32-bit JVM; for other 64-bit platforms, Serena Release Automation uses a 64-bit JVM, as the following table illustrates:
